' This invention relates generally tothe color-finishingof pencils and the like and,more particularly, to a certain new and useful process and apparatus for color-striping pen- 5 oils and the like in the finishing thereof.

My invention has for its chief objects to provide a pencil, pen-holder, or the like finished in two or more colors arrangedin a' plurality of longitudinal stripes or panels on the pencil or other such body a highly attractive and artistic manner and appearance; to provide a process or method for colorstriping a pencil-body or the like in a simple, expeditious, and highly economicaland etficient manner; and to provide anew and novel apparatus forcarrying out and practicing such process or method especially adapted for the continuous =or, s'o-called mass production of pencils and the like color-finished in accordance with -rny invention. 'i' 1" And with the above andother'objects in view, myinvention resides in the novel fea tures of 'form, construction, arrangement, and combination of parts and in the method of use thereof, all as hereinafter described and pointed out in the claims.

My invention may be employed for colorfinishing round, hexagonal, octagonal, flat, andoval pencils and the'like, and my new process of color-finishing. consists, generally, in successively coating a pencil-body or the like with preferably dissimilar colors and removing portions of the overlaid or second coat for exposing both colors-on the pencil. And for, carrying out the process, I providean aps paratus adapted to be worked in stages, which includes a pencil feederA, a color-applying means or paint-pot B co-operatingwith a so called first-coat wiper G,complementaryto suitable drythe particular pencil-body, a ing device D, a second ;pencil;-cfeeder -E, ;a second color-applying means or paint-pot F co-operating with a so-called secondrcoat Wiper G complementary only in *part to'the particular pencil-body, and, preferably, a suitable conveyer H fortransporting the finished work, all as best seen inFigurefl. If more--thantwo ,paint-coatsare to be applied, .to, the particular pencil additional successive drying, color-applying, and wipe ing stagesmaybe provided, as may beYrequirecl suitablyfor the, purposes intended; :Referring now more in detail and by refures l .to 4-, inclusive,Lillustrate oneor the preferred form of my invention, especially, though 'not exclusively,adaptedE-for color} finishing an hexagonal-bodiedor like, prisfm ic pen il K: i

For such purp rably includes a suitable paint-container? 1,

having in two of its opposing walls registers ing aperturesQ, 3, the aperture 2 being prof ing 4.

Disposed in co-operation and registration with the opposite aperture 3, is the first-coat wiper C, which comprises a suitably formed body member 5 constructed of a rubber or like elastic material for yieldingly or resiliently engaging the projected pencil. The body member 5 of the wiper C tapers from its outer smaller end in a frusto-conical shape and at its inner end has a flange 6 adapted to be engaged by an annular suiting the pencils K in endwise abutting relation successively through the pot B and the wiper O. In the pot B I provide a body of suitable liquid paint, enamel, or like surface covering material, in tint a of the color selected for the first or under-coat of the pencil K. The thick coat of the paint a, adhering to the surface of the unmersed pencil K while passing through the pot B, is

suitably smoothed on the pencil by the walls ofv the passage'S of the wiper'C, which, as most clearly seen-in FigureS, resiliently embrace or grip the entire peripheral surface ofthepencil, in such manner as to remove and return to the pot B any surplus paint a and leave a thin film or coating of the paint a uniformly over the surface of the now painted or first colored'pencil K.

"I prefer to arrange the apparatus so that the painted or colored pencils K discharge from the wiper C onto a suitable conveyer or drying device D, the latter being shown, in the present instance, as a drying wheel or; revolving carrier on which the pencils K i remain until the paint a has dried, whereupon the now dried pencils K are disposed by the device D in suitable positionfor delivery, manually or otherwise, to the feeding device E, which fe'eds'successive pencilsK', preferably in endwise abutting relation, to and through the paint-pot F, which is substantiallylike the pot B, that is, includes a receptacle 1 spaced registering apertures 2, 3, and packing 4. In like manner, the second coat wiper G is mounted by a retainer 7" on the pot F, thewiper G also including a bodyportion 5 and flange 6, substantially similar to, and interchangeable on the pots B, F, with the wiper C, for apurpose later appearing. The wiper G, thus disposed'on the potF suitably. to yieldingly receive and resiliently grip the successive pencils K fedtherethrough, is constructed'of rubber or like yieldablegorelastic material, like the wiper C, but difiers therefrom in having its pencil-- receptive passage or bore 9 of a cylindrical cross-section, whose walls yield in their engagement with the corners 10 of the meeting faces .11of the pencil'K and are hence, in such respect and position, only in part complementary to the pencil-body.

In the pot F, I provide a suitable liquid paint 6 of the'colo r selected for the second or overcoating of the pencil, a thick coat of the paint I) adhering to the immersed undercoat- 'ing. a of the pencil K passing through the pot F. The so coated pencil then longitudinally shiftably engages the normally cylindrical but elastic walls of the passage 9, which are sufficiently distorted by reason of the prismaticshape of the pencil to leave a slight clearance 12, shown greatly exaggerated in Figures 2 and 4, between said walls and the respective faces 11 of the pencil-stock, for removingsurpluspaintfrom said faces 11 while leaving a coating or film of paint thereon rather thicker than the film of paint a for providing a good body color to the pencil. Q

However, at the corners or edges 10 of the pencil body, the elastic walls of the passage 9 are compressed upon the pencil stick in such manner as to scrape and substantially remove all of the coating 5 from, and thereby expose, the under coat a at said corners 10. ofthe pencil, as best'seen in Figure5, the finishedpencil. being-designated at K, the overcoating being shown at b, and the undercoating at a. It will be seen that the body color of the pencil'K is formed by the second coating 6 applied in panel-like formation on the respective faces 11: of the pencil, and that such panels are provided with an edging or striping, as may be said, of the color of the first or undercoating exposed at the corners'lO of the pencil, thus producing a two-toned color eflect in a highly'efl'ective, artistic, and inexpensive manner. I

I prefer to discharge the pencils K on to a suitable conveyor or drying device H, which is shown, in the present instance, as a straight line conveying device, on which the pencils K preferably 6 has dried. V

In Figure 6 is shown a modified form'of second-coat wiper G also adapted for use with a hexagonal or like peripherally angular pencil L. The wiper G" is "substan tially in use, construction, and material like the wiper G, and hence in suchrespects is remain until the second coatnot more particularlydescribed here. The

wiper G however, differs from the wiper G in the respectthat the walls ofthevpencilreceptive passage'or'bore 1,8 of the wiper G" have'longitudinal parts 14 adapted toresilithe first. coat a thereat,.asrbestseenin Figure 7. Intermediate the parts 14, the walls of the passage 13 are relieved or provided with longitudinal channels 16 so as to cause the walls of the passage 13 to be substantially complementary only in part to the pencil body and hence spaced from the correspond- In Figure 8 is shown a further modified,

form of second-coat wiper G, adapted for use with a cylindrical. or like peripherally curved pencil M. The wiper G is substantially in use, construction, and material like the wiper G, and hence in such respects is also not more particularly described here. The wiper G, however, differs from the wiper G in the respect that the walls of the pencil receptive passage or bore 18 of the wiper G are circumferentially interrupted providing longitudinally extending transversely arcuate parts 19, whereby the wiper G-' is adapted to yieldingly or resiliently engage successive correspondingly circumferential panel-like portions 20 of the pencil-body M for scrapingly removing therefrom the second coat of color and hence exposing the first coat a thereat, as best seen in Figure 9. In termediate the parts 19, the walls of the passage 18 arerelieved or provided with longitudinal grooves or channels 21, so as to cause the walls of the passage 18 to be substantially complementary only in part to the pencil body and hence spaced from corresponding longitudinally extending arcuatc portions 22 intervening the portions 20 of the pencilbod M which hence retain the second coat of color Z). also as best seen in Figure 9.

I miq'ht add that the process of color-finishing the pencil when employing the wiper G, is also substantially the same as that when using the wiper G, except that, in addi- 7 tion to the differences above pointed out, for the first-stage wiper C is substituted a wiper complementary to the pencil-body M, which modification of the process may be readil 7 eiiected, for example, by substituting a wiper G for the wiper C, as will be readily understood.

It will be obvious that wipers having the general characteristics of those shown may be constructed for use with pencils of prismatic contours differing from those illus trated. For example, the second stage wipers G, G may beinodified for use with flat sided carpenters pencils and the like, a suitable modification being also made in the first stage wiper C. Likewise, the second-stage wiper G may be modified for use with oval or elliptical pencils, the wiper C being, of

course, correspondingly modified, andv other changes and modifications will, with the aid of this disclosure, readily suggest themselves to those; skilled in the'art ofpencil manufacture. j a j p It will be'seen that my invention accomplishes its objects, by providing a new and novel process for the production of striped pencils and apparatus therefor, which in simplicity, adaptability, facility and economy of use andemployment is of highly efficient and practical utilityin theart of pencil colorfinishingn; m 7 n a I mightadd that,while Ihave employed the conventional standards as a matter of convenience in preparing the drawings, and

hence shown the color a asfblue, and the color bas r r ed, so as to provide fora red body with blue striping, 'I' prefer in practice to employ a dark body orover color 6, as red,

blue, green or the like, and alight ground or under color a, as white, yellow, goldfor the like, such as may provide the most agree-- able contrasts in the finish of the pencil. It is to bennderstood that, while for convenience and simplicity of terminolog in description,I have employed the term pencil or, pencils in the foregoing specification and appended claims, I desireto be under-.

fountain pens, so-calle'd mechanical pencils,

and other like or similar elongated bodies or shells adaptable in form or purpose, for

color-finishing, as hereinbefore set forth. It Isl/0138 further understood that any suitable contrastmg colors ortmts may be employed, and'that changes and modificw tions in the dctails'of the process and in' the apparatus may be made and substituted for those herein shown and described w'ithoutdeparting from the nature and principle of my invention, as defined in the appended claims;
